Trans-sacral bar osteosynthesis provides low mortality and high mobility in patients with fragility fractures of the pelvis.

Operative treatment of osteoporosis-associated fragility fractures of the pelvis (FFP) and the sacrum is advocated with immobilizing or longstanding pain, fracture progression and displacement. We analyzed clinical outcomes regarding mobility, quality of life, and mortality of patients with FFP treated with trans-sacral bar (TB) osteosynthesis through S1. Demographics, clinical data, and operation-related data of patients with an FFP treated with TB were acquired from chart review.

[Anatomical aspects regarding the endoscopic release of the nervus interosseus anterior].

Background: Decompression of the anterior interosseous nerve can be performed in an open operative exploration or endoscopically. Using an endoscopic decompression superficial anatomical landmarks serve as reference point. The aim of the study was to determine the location of the distribution of the median nerve in relation to the elbow joint in order to facilitate preparation during endoscopic decompression.

Custom-made wrist prothesis (UNI-2™) in a patient with giant cell tumor of the distal radius: 10-year follow-up.

Wrist endoprosthesis is still an exceptional indication compared to the prosthesis of large joints, especially when a rescue surgery procedure of the wrist is no longer possible and the complete wrist arthrodesis is to be considered the ultima ratio. However, a suspended function in the wrist is accompanied by a significant restriction in the patient`s daily life. Using the fourth-generation endoprosthesis, the situation regarding long-term results for the hand has already improved.

[Revision surgery after total wrist arthroplasty].

Background: Wrist arthroplasty is still an exceptional indication in the field of hand surgery. In recent years, it has become increasingly accepted as an alternative to wrist arthrodesis as the ultima ratio for panarthrosis or similar destruction of the wrist. In particular, the patient's desire for functional integrity also plays an important role.

"Cat and dog bite injuries of the hand: early versus late treatment".

Introduction: Animal bites of the hand are common injuries in the emergency department. Serious complications may occur if those injuries are not treated adequately. The purpose of the study was to examine if there is a difference between the treatment of animal bite injuries at an early stage (first treatment within the first 24 h after injury, group I) versus a later stage (first treatment more than 24 h after injury, group II) retrospectively.

Minimal-invasive stabilization of anterior pelvic ring fractures with retrograde transpubic screws.

Background: In the vast majority of patients with pelvic ring lesions, there is a combination of fractures of the posterior and anterior pelvic ring. Anterior fractures are painful and contribute to loss of stability of the pelvic ring. For these reasons, stabilization of pubic rami fractures is recommended together with posterior pelvic ring fixation.

Progress of instability in fragility fractures of the pelvis: An observational study.

Unlabelled: Fragility fractures of the pelvis (FFP) are an increasing entity among elderly persons. Characteristics are different from high-energy pelvic trauma. Little is known about the natural course of FFP in conservative and after operative treatment.

Practicability of a locking plate for difficult pathologies of the scaphoid.

Introduction: Headless compressions screws are the most implanted devices for scaphoid fractures and nonunions. For cases when screw osteosynthesis is not possible, a special locking plate for scaphoid reconstruction has been developed. The purpose of this study was to evaluate the safety and practicability of this device for difficult scaphoid pathologies.

Long-term outcome of fingertip reconstruction with the homodigital neurovascular island flap.

Introduction: Fingertip injuries are frequent and several surgical strategies exist to reconstruct the amputated part and restore function and appearance. Yet, long-term results are rarely published. The purpose of this study was to examine the long-term clinical outcome of neurovascular island flaps for traumatic fingertip amputation of Allen type III/IV injuries.

Results after arthroscopic treatment of central traumatic lesions of the triangular fibrocartilage complex.

Introduction: Injuries of the triangular fibrocartilage complex (TFCC) are of high clinical relevance; however, the clinical evidence for treatment is poor and long-term results are rarely published. The purpose of this study was to evaluate the clinical outcome of symptomatic central traumatic lesions of the TFCC (Palmer 1A) following arthroscopic debridement.

Materials And Methods: Between 2007 and 2013, 87 patients were arthroscopically diagnosed with Palmer 1A lesion and accordingly treated with debridement.

[Wrist arthrodesis with a fixed-angle, "low-profile" fusion plate without carpometacarpal joint fixation].

Objective: Total wrist arthrodesis to improve functional use of the hand by reducing pain and increasing grip strength.

Indications: Painful destruction of the radio- and midcarpal joints.

Contraindications: Analgesia and satisfactory hand function after motion-preserving surgical or conservative treatment.

[Primary intervention in Dupuytren's disease].

Partial aponeurectomy as the state-of-the-art treatment in Dupuytren's disease is indicated when minimally invasive forms of treatment, such as needle aponeurotomy or percutaneous collagenase injection, are not possible due to the advanced stage of the disease or the morphology of the contracture. Even in earlier stages of Dupuytren disease partial aponeurectomy has advantages in comparison to minimally invasive forms of treatment. These advantages are lower recurrence rates as well as less persistent residual contractures, especially in the proximal interphalangeal joint.

[Fractures of the thumb ray].

Fractures of the first thumb ray are common and need accurate differential treatment to restore gripping hand functions. Displaced fractures of the distal and proximal phalanx of the thumb are often treated with screws or Kirschner wires. Stable fractures can also be treated non-operatively.

Current concepts for the treatment of acute scaphoid fractures.

Fractures of the scaphoid are common injuries, accounting for approximately 80 % of carpal fractures. Differentiation between stable and unstable fractures (Herbert classification) cannot be made with conventional X-rays, so evaluation by computed tomography should additionally be performed. Under most circumstances, minimally invasive surgery with cannulated screws is the treatment of choice.

[Bone Necrosis of the Hand].

The bone necrosis of the hand is a common disease of the bone-cartilage complex. In principle, every bone of the hand can be affected. Compared to other osteonecroses of the hand the necrosis of the lunate occurs most frequently.

[Plastic surgical management in lower extremity sarcoma reconstruction].

Tumors in the lower extremity with a critical size of over 5 cm diameter should principally be tested for being malignant soft-tissue sarcomas. If a soft-tissue sarcoma is present, radical oncological resection with sufficiently wide surgical margins is the most important cornerstone of curative therapy. No neoadjuvant or adjuvant treatment (radiotherapy or chemotherapy) can replace this treatment approach.

Evidence-based flexor tendon repair.

The goal of flexor tendon repair is to achieve normal range of motion of the finger or thumb. The surgical approach depends on the level of injury. Multistrand core suture repairs are recommended for primary flexor tendon repair.

Mobilization of CD34+-progenitor cells in patients with severe trauma.

Circulating CD34+ progenitor cells () gained importance in the field of regenerative medicine due to their potential to home in on injury sites and differentiate into cells of both endothelial and osteogenic lineages. In this study, we analyzed the mobilization kinetics and the numbers of CD34+, CD31+, CD45+, and CD133+ cells in twenty polytrauma patients (n = 13 male, n = 7 female, mean age 46.5±17.

[Scaphoid fractures and pseudarthrosis of the scaphoid].

Scaphoid fractures are by 80 % the most common fractures of the carpal bones. Detection and treatment can be delayed due to only slight clinical symptoms, which are often shown by acute injuries of the scaphoid. Pseudarthrosis of the scaphoid developing arthrosis of the wrist or even a carpal collapse can be the consequence.

[Treatment of phalangeal fractures using the mini-hook plate. An alternative for surgical fixation of small phalangeal bone fragments?].

Background: Fixation of the small bony fragments of the phalanges is often difficult. In this study a clinical and radiological evaluation was carried out after operative treatment using the mini-hook plate.

Patients And Methods: Between 2003 and 2006 a total of 36 fractures were treated operatively using the mini-hook plate.

Purpose: The purpose of our study was to determine the biomechanical properties of three different implants utilized for internal fixation of a supracondylar femur fracture. The retrograde supracondylar nail (SCN), the less invasive stabilization system plate (LISS) and the distal femoral nail (DFN) were tested and their biomechanical properties compared.

Methods: Twenty pairs of fresh-frozen human femura were used.

Are there any differences in various polyaxial locking systems? A mechanical study of different locking screws in multidirectional angular stable distal radius plates.

Numerous angular stable plates for the distal radius exist, and technically based comparisons of the polyaxial locking interfaces are lacking. The aim of this mechanical study was to investigate three different locking interfaces of angular stable volar plates by cantilever bending: VA-LCP Two-Column Distal Radius Plates 2.4 mm (Synthes® GmbH, Oberdorf, Switzerland), IXOS® P4 (Martin, Tuttlingen, Germany) and VariAX™ (Stryker®, Duisburg, Germany).

Intraoperative C-arm CT imaging in angular stable plate osteosynthesis of distal radius fractures.

The purpose of this study was to analyze the practicability and benefit of intraoperative C-arm computed tomography (CT) imaging in volar plate osteosynthesis of unstable distal radius fractures. During a 1 year period, intraoperative three dimensional (3D) imaging with the ARCADIS Orbic 3D was performed in addition to standard fluoroscopy in 51 cases. The volar angular stable plate oesteosyntheses were analyzed intraoperatively and, if necessary, improved immediately.
